My Father’s Dragon by Ruth Stiles Gannett, illustrated by Ruth Chrisman Gannett, 1948.

This is a fantasy book where the author tells a story about her father’s adventures rescuing a dragon when he was a boy.

It all starts when the boy, Elmer Elevator, brings home an alley cat that he found. However, his mother doesn’t like the cat and doesn’t want Elmer to keep her. When he tries to feed the cat secretly, she throws the cat out and punishes Elmer. The boy and the cat take a walk in the park together, and the boy confides his wish to learn how to fly airplanes when he grows up. The cat says that he doesn’t have to wait until he grows up to learn how to fly.

The cat explains that she has traveled a great deal, and not too long ago, she visited the Wild Island, which is inhabited by wild animals. The island is divided in half by a river inhabited by crocodiles. Normally, the animals have to take the long way to get around the river to avoid being eaten by the crocodiles, but a few months before the cat visited the island, a baby dragon fell of his cloud and landed next to the river with an injured wing. The other animals on the island captured the poor baby dragon, and when his wing healed well enough for him to fly, they started forcing him to carry passengers and cargo over the river. They work the poor baby dragon too hard and mistreat him. The cat made friends with the little dragon and wanted to help him but didn’t know how because she couldn’t untie the rope that holds the dragon prisoner. The cat suggests to Elmer that the dragon would probably be happy to give him a ride if he helps to free him, and Elmer decides to do just that. Besides, he’s angry with his mother for mistreating the cat and doesn’t mind leaving home for awhile.

The cat decides that she’s too old to travel, so she stays behind, but she helps Elmer to prepare for the trip. Elmer stows away on a ship to the nearby Island of Tangerina and gets to the Wild Island by climbing over the rocks between them. When he reaches the Wild Island, he decides to look for and follow the river, but he has to be careful of the animals on the island.

Elmer is found by some tigers who say that they’re hungry and curious to know what little boys taste like. However, remembering some of the cat’s advice, he offers the tigers some chewing gum because (apparently) tigers love it. He also tells them that it’s special chewing gum that will change colors when they chew it, and then, they’ll be able to plant it in the ground to grow more chewing gum. The tigers fall for it and forget about Elmer, who sneaks away.

Elmer also has a dangerous encounter with a rhinoceros after he drinks from his “weeping pool.” The rhino wants to toss Elmer into his pool to drown him, but Elmer asks him what he has to weep about. The rhino says that he’s upset that his tusk is no longer as white and pretty as it used to be, and Elmer gives the rhino his toothbrush and toothpaste. The rhino lets Elmer go and begins using the toothbrush to clean his tusk, but by now, the boars have realized that there is someone on the island who doesn’t belong.

Elmer continues onward, helping a lion with a messy mane and a gorilla with fleas and befriending the crocodiles by offering them all lollipops, until he finally finds the dragon and rescues him. They fly away from the island together, but it’s not the end of their adventures.

There’s a reason why the author and illustrator’s names are very similar but not identical. If you read their short biographies, they explain that the illustrator was the stepmother of the author.

This book is a Newbery Honor Book, and it’s also the first in a trilogy about Elmer and the dragon and their adventures together. It’s available to borrow and read for free online through Internet Archive (multiple copies).
